Parents are mad at me for wanting a baby?

So I’m 21 years old, my boyfriend and I both have full times jobs and I’ve moved in with him…

Before I moved out I wrote down a prayer saying I wanted his baby, because at the time I thought I was pregnant and I wanted it. After I wrote down the prayer I put it inside my pillow case. After I moved out my dad took my pillow and started sleeping with it, last night my dad for some unknown reason unzipped the pillowcase, (it’s a bamboo pillow and without it’s protective covering it’s got a tacky feeling) and saw the prayer…. He text me and asked “what the hell it was” so I told him and told him not to snoop.

I feel like my privacy was violated, I literally started the note with “Dear God” and my parents continued to read it…

Now that we’re actually TTC I don’t know if I’ll want to tell them when I get pregnant in fear of their reactions.
